DIY Voice Assistant based on the GLaDOS character from Portal video game series.

• Designed for Raspberry Pi
• Written mostly in Python
• Work in progress

1. Local Trigger word detection using PocketSphinx
2. Speech to text processing using Google's API (for now)
3. GLaDOS Text-to-Speech generation using https://glados.c-net.org/
4. Storing of generated audio samples locally for instant answers in the future
5. Animatronic eye control using servos
6. Round LCD for an eye to display display textures

Tight integration with Home Assistant's local API:

• Send commands to Home Assistant
• Can read and speak sensor data
• Notification API, so Home Assistant can speak notifications aloud

• Clock
• Control lights and devices
• Weather and forecast
• Add things to shopping list
• Read sensor information
• Random magic 8-ball answers
• Tell jokes
• Judge you and be mean
• Advanced fat-shaming
• Log stuff and gather training data locally

Note: The code is provided as reference only.

You can add glados.py to your crontab file or run it manually.

crontab -e
@reboot python3 /home/username/GLaDOS-Voice-Assistant/glados.py

Additionally you can configure the ReSpeaker at startup by adding following lines to root's crontab:

sudo su
crontab -e
@reboot bash /home/username/GLaDOS-Voice-Assistant/hardware/ReSpeaker/ReSpeaker_Startup_Config.sh
@reboot python3 /home/username/GLaDOS-Voice-Assistant/hardware/ReSpeaker/ReSpeaker_Turn_off_Pixelring.py

List of reference hardware what nerdaxic is developing on, models might not need to be exact. Not a full bill of materials.

Audio amp is powered from Raspberry GPIO 5V line and ReSpeaker board from USB to avoid ground loops and noise issues.

Mechanics are powered from their own power supply to allow more power for the servos and prevent brown-outs.
